In the article \u201cMultiswitchable photoacid\u2013hydroxyflavylium\u2013polyelectrolyte nano-assemblies<\/em>\u201d Alexander Zika and Franziska Gr\u00f6hn describe the development of a novel reversible multi-switchable system consisting of a cationic polyelectrolyte, a hydroxyflavylium molecule (Flavy), and a photoacid.*<\/p>\n\n\n\n

Ternary assemblies with sizes in the hundred-to-few hundred nanometers range in aqueous solution exhibit a multi-addressable size and shape.*<\/p>\n\n\n\n

The concept exploits the unique property of the photoacid to form a more highly charged molecule and to switch the Flavy molecule in the same step when excited by light irradiation.*<\/p>\n\n\n\n

Due to the network of possible reactions of Flavy, self-assembly can be accessed and triggered in a number of ways.*<\/p>\n\n\n\n

While their study focused on the first proof of concept and the relation of molecular and nanoscale switching, a deeper understanding of the molecular binding effects may be considered in future studies.*<\/p>\n\n\n\n

The type of the photoacid-based assembly presented in the article bears potential, for example, for delivery where the assembly property changes may provide a desirable transformable platform for tunable and smart transport.*<\/p>\n\n\n\n

Atomic force microscopy (AFM) with NanoWorld Ultra-short Cantilevers<\/a> USC-F0.3-k0.3 <\/a> in tapping mode was used to investigate the structure.*<\/p>\n\n\n\n
